I have this same exact laptop
Dell Inspiron i15R-2369sLV 15-Inch Laptop
Also only 2 months old but it has had this issue since day 1. The Internet would disconnect every 5 minutes and I would have to troubleshoot it to get it back to work and it only happens to this computer all my other computers work fine. I have sent the computer back to dell depot for repair 2 times already and I'm finally getting a system exchange because they haven't been able to solve the issue I believe there is something faulty from the manufacturer on this specific systems.
